Does anybody have one? I had posted before about my 6 year old learning to read and it's going slowly. I saw this on sale at Target with a coupon and picked it up. I haven't decided if I should keep it for a Christmas gift. I don't want to overwhelm him, as he as reading at school, he reads 3 or so books to me at night, and I read 15 minutes(at least) to him every night, but I also want him to succeed. I am wondering if it's worth the expense or not.
